Rebecca Law 87556687ab This is the first PR in the story to create a suspend service feature.
- Renaming /service/<id>/deactivate to /service/<id>/archive to match language on the UI.
  - Will need to update admin before deleting the deactive service method
- Created dao and endpoint methods to suspend and resume a service.
- I confirm the use of suspend and resume with a couple people on the team, seems to be the right choice.

The idea is that if you archive a service there is no coming back from that.
To suspend a service is marking it as inactive and revoking the api keys. To resume a service is to mark the service as active, the service will need to create new API keys.
It makes sense that if a service is under threat that the API keys should be renewed.

The next PR will update the code to check that the service is active before sending the request or allowing any actions by the service.
